What is zkPorter?
zkPorter is a Layer 2 scaling solution that leverages zero-knowledge succinct non-interactive arguments of knowledge (ZK-SNARKs) to enable instant transaction finality and high throughput. Built on Ethereum's infrastructure, it promises to deliver near-instant and secure transactions at a fraction of the cost.
Key Features
- 500,000 Tps throughput
- Instant finality with validity proofs
- Post-Quantum cryptographic algorithms
Why It Matters
zkPorter addresses Ethereum's scalability limitations by offloading transaction processing to an off-chain environment with cryptographic proofs for security and consistency. This enables mass adoption of dApps without compromising decentralization.
How zkPorter Works
The core of zkPorter is its use of ZK-SNARKs to validate off-chain transactions without requiring full trust in the operator. Here's a simplified workflow:
1. Transaction Batching
User transactions are collected in batches and processed off-chain by a network of sequencers.
2. Proof Generation
Sequencers generate cryptographic proofs for the batch using ZRO16 zk-SNARKs.
3. Verification onchain
The generated proof is posted on Ethereum for verification by a small set of provers.
4. Final Execution
On verification, transactions are finalized with instant settlement guarantees.
zkPorter Implementation
// zkPorter Transaction Batch
const batch = zkporter.createBatch(transactions);
batch.addProof(prover.generateProof()); // ZK-SNARK proof generation
// Verification request to Ethereum
const verification = new EVMVerifier();
verification.submit(batch.proof, {
gasLimit: 100000,
network: 'ethereum-mainnet'
});
// Finalize transactions
await zkporter.finalizeTransactions(batch.id)
.on('confirmation', (event) => {
console.log('Finalized:', event);
});
